Tired and disappointed. That’s not only the way Ralf Dujmovits feels, he also sounds like this. The 55-year-old climber from Germany talks quietly and slowly, when he tells me via satellite phone about his failed summit attempt on Everest without bottled oxygen. On Saturday, Ralf had turned around at an altitude of 8,580 meters, just before the Second Step, the most striking rock step on the Northeast Ridge: “That was bitter.”

Mount Everest has shown his teeth again on the past weekend – just on the day when eight climbers were on their summit push without bottled oxygen. Contrary to expectations, on Saturday wind gusts and snowfall in the summit area made the ascent difficult. The result: two summit successes without breathing mask on the north side, one on the south side. Two climbers, who used supplemental oxygen at all and reached the highest point at 8,850 meters. And three summit aspirants, who turned back because of concerns for their health.

What a pity! Ralf Dujmovits has not been able to fulfill his dream of reaching the summit of Mount Everest without bottled oxygen. The 55-year-old turned back at an altitude of 8,500 meters. From Camp 3 at 8,300 meters, he telephoned his life partner, the Canadian climber Nancy Hansen. “He had to turn back at 8,500 m because a storm blew in: 40 kph winds with snow. He was losing feeling in his hands and feet,” Nancy wrote on Facebook. “As you can imagine, he is extremely disappointed. The weather just didn’t allow for a summit.” Ralf’s wise decision demands respect and shows that he was still in control of himself.

Ralf Dujmovits is close to his big goal. In his eighth attempt, the 55-year-old finally wants to scale Mount Everest without bottled oxygen. Ralf is only about eight hours of ascent away from the highest point on earth at 8,850 meters – if everything goes well. Today Dujmovits, according to his life partner Nancy Hansen, reached Camp 3 on the Tibetan normal route at 8,300 meters, from where he called her by satellite phone. There had been a thunderstorm for the last hour, Ralf told the Canadian. It had taken him five hours to climb the 600 vertical meters from Camp 2. “He feels a little tired, but he sounds very alert and normal,” Nancy wrote on Facebook. “He will drink a lot now, rest a few hours, and leave for the summit at 1am Nepali time (1.15 pm Friday in Canada, 9.15 pm Friday in Germany).”

So far, the summit attempts of the climbers, who are currently tackling Mount Everest without bottled oxygen, are on schedule (with one exception, see below). According to his life partner Nancy Hansen, Ralf Dujmovits today reached Camp 2 on the Tibetan north side of the highest mountain on earth: “Ralf just called me from 7,700 m, where he will sleep for the night,” the Canadian climber wrote on Facebook. “It is stormy now, but the winds should come down. Tomorrow he will move up to 8,300 m. He feels good!” The 55-year-old has already – as the only German climber so far – scaled all 14 eight-thousanders. Only on Everest in 1992 he had used a breathing mask. The current attempt without bottled oxygen is his eighth and in his own words the “definitely last one” on Everest.

If everything works, there could be a “topless” party on the summit of Mount Everest next Saturday. Some climbers who want to scale the highest mountain on earth without breathing mask have started their summit attempts. Among those who set off from the Advanced Base Camp on the Tibetan north side was Ralf Dujmovits. The 55-year-old, so far the only German who has scaled all 14 eight-thousanders, wants to succeed in his eighth attempt climbing Everest without supplemental oxygen. In his successful attempt in fall 1992, Ralf had used a breathing mask above the South Col, due to bad weather. All other eight-thousanders he had climbed without bottled oxygen. His plan now: today North Col (7,050 m), tomorrow Camp 2 (7,700 m), on Friday Camp 3 (8,300 m) and on Saturday “hopefully towards the summit” (8,850 m), as Ralf writes to me: “I am confident, I feel good and I think that the extremely warm temperatures (probably minus 20 degrees Celsius) might help me.”

“I believe he was a totally happy person when it happened,” said Robert Boesch, the Swiss photographer and mountaineer, at the commemoration for his friend Ueli Steck, who had fallen to death from an altitude of about 7,600 meters on Nuptse on 30 April. Every SMS Ueli had sent from Everest Base Camp before had conveyed the message: Everything is perfect, motivation as well as fitness. Boesch believes that it was a spontaneous decision of the 40-year-old not to ascend to Everest South Col, as originally planned, but to climb Nuptse. “The conditions must have been good, otherwise he would not have been so early so far up,” said Robert. Surely Steck had climbed “in a flow”. Why he fell, could not be clarified: “That doesn’t matter, that’s just climbing. He did not have the quantum of luck he would have needed.”

The summit of Mount Everest was probably quite crowded today. From the north side, maybe 60 climbers tried to reach the highest point on earth at 8,850 meters, Ralf Dujmovits wrote on Instagram. The number of summit aspirants on the Nepali south side might have been much higher. Dujmovits, the so far only German who has climbed all 14 eight-thousanders, wants to reach the summit of Everest without bottled oxygen. The 55-year-old plans to wait for the current run being over and only then start his own attempt: “At my age climbing without supplemental oxygen one needs to climb at a very steady pace – can’t speed up for overtaking (loosing too much body warmth) or can’t wait at typical cueing points (loosing body warmth by just waiting).”

While for many climbers the decisive phase on the highest mountain on earth has begun right now, Dominik Mueller is already packing his bags. As reported before, the German expedition leader reached the 8850-meter-high summit of Mount Everest from the Tibetan north-side on Tuesday, as well as one of his clients. Two other members of his team turned around at 8,550 respectively 8,600 meters. “All are fine, not even a single wound,” says Dominik when I reach the 46-year-old head of the expedition operator Amical alpine via satellite telephone in the Advanced Base Camp at 6,300 meters.

Dominik, first of all congratulations. How was the weather and the conditions on the mountain during your ascent?

Nobukazu Kuriki has changed Everest sides. The 34-year-old Japanese today reported on Facebook from Gorak Shep, the 5207-meter-high last inhabited settlement below Everest on the Nepalese south side. Apparently, Kuriki has managed the necessary formalities with the Nepali authorities. Previously, Nobukazu had pitched his tent on the Tibetan north side: on the Central Rongbuk Glacier below Everest North Face. The reason for his change of location, says Kuriki, was that he had changed his previous plan for the ascent. Originally, the Japanese had wanted to climb the North Face, solo and without bottled oxygen, via the so-called “Supercouloir Route”, a system of gullies that stretches almost through the entire wall.

The spell is broken. For the first time this spring, climbers have scaled the summit of Mount Everest also from the Nepalese south side of the mountain. An employee of the Ministry of Tourism informed from the Base Camp that today 14 climbers reached the highest point on 8,850 meters. The route is now secured up to the summit with fixed ropes. According to consistent reportsthree members of an expedition of the British Gurkha military brigade were among the successful climbers.

Everybody is writing about how crowded Mount Everest is. “The mountain is almost completely deserted,” Ralf Dujmovits tells me today via satellite phone. The only German who has so far climbed all 14 eight-thousanders has just returned from his second acclimatization climb on the Tibetan north side of Everest. He spent a night in Camp 2 at 7,700 meters, then he descended, as scheduled, to the Advanced Base Camp (ABC) at 6,300 meters.

Actually, the first summit successes on Mount Everest had been expected for the past weekend. However, the Sherpa team that wanted to fix the ropes up to the highest point on 8,850 meters on the Nepali south side of the mountain had to turn around because of strong winds. And now it’s snowing. Snowfall is also expected for the next days. After all, the weather forecast for this week predicts little wind in the summit area. Maybe something will be still possible. This does not apply to Ryan Sean Davy. The 43-year-old South African was caught in Everest Base Camp without permit and sent back to Kathmandu.

He would have liked that. At Tengboche Monastery in the Khumbu area, at almost 4,000 meters, with a view to Mount Everest, Lhotse and Ama Dablam, Ueli Steck’s ​​family bid farewell to the Swiss top climber during a Buddhist ceremony. The 40-year-old had fallen to death on Sunday on the 7861- meter-high Nuptse. “According to the Nepali tradition, the deceased was cremated in an impressive three-hour ceremony,” Steck’s family informed via Facebook. Uelis wife Nicole, his parents and parents-in-law took part. “The family perceived the ceremony as very solemn and impressive, sad and at the same time liberating.” The family will take a part of the ashes back to Switzerland, where a public memorial is planned for friends, acquaintances and companions. Place and time are not yet fixed. On Ueli Steck’ homepage ​​an online book of condolence was established.
